  1. 11. Host-pathogen interactions between Francisella tularensis and Drosophila melanogaster

    Författare :Malin Vonkavaara; Svenja Stöven; Ingrid Faye; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arthropod vector; JNK; lipopolysaccharide; antimicrobial peptides; Clinical Bacteriology; klinisk bakteriologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Francisella tularensis is a highly virulent Gram-negative bacterium causing the zoonotic disease tularemia. Arthropod-borne transmission plays an important role in transferring the disease to humans. F. LÄS MER

  3. 12. MHC polymorphism and host-pathogen interactions: The case of Borrelia in its reservoir host, the bank vole Myodes glareolus

    Författare :Kristin Scherman; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Host-pathogen interaction; Negative frequency dependent selection; Myodes glareolus; Borrelia;

    Sammanfattning : The major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS).

  4. 13. Host-Pathogen Interactions in Pseudomonas aeruginosa Invasive and Respiratory Tract Infection

    Författare :Magnus Paulsson; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pseudomonas aeruginosa; vitronectin; Respiratory tract infections; Innate Immunity; outer membrane vesicles; outer membrane proteins; beta-lactamase; ciprofloxacin; combination treatment; bacteraemia; Complement escape;

    Sammanfattning : Pseudomonas aeruginosa is an opportunistic bacterium that causes debilitating infections when the immune defence is compromised. It possesses an arsenal of virulence traits to colonize most compartments of the body and is often highly resistant against commonly used antimicrobial drugs. LÄS MER

  5. 14. Roles in innate immune receptors : host – pathogen interactions and strengthening vaccines

    Författare :Sanna Nyström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During the past decades our knowledge of innate immunology has increased drastically. This has improved our understanding about how innate immune cells can distinguish self from non-self, commensal bacteria from pathogens, and how it affects later adaptive immune responses. LÄS MER

  7. 15. Tissue microbiology : an integrated approach for intravital studies of host-pathogen interactions

    Författare :Ferdinand Xiankeng Choong; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A bacteria infection in the living host is the summation of a myriad of interactions. Reductionistic and sacrificial experiment models cannot replicate this complexity. The Tissue Microbiology approach overcomes this by allowing the live host and pathogen to control all facets of the infection model. LÄS MER
